I had the all too familiar Nigel O'Hara experience - bought something which was not available, then cancelled after many promises of delivery date being confirmed very soon. I too found it very difficult to obtain a refund, but I did eventually manage it. I sent Nigel O'Hara many emails and made it clear that I would take the matter to small claims court and trading standards if I was not refunded. I also made it clear that Nigel O'Hara would be charged for my time and the court costs if I was forced to go via small claims court. Eventually this worked. Retailers have 30 days to process a refund by law, which is unnecessarily long - refunds are very quick and easy to process. But my advice is to avoid Nigel O'Hara if possible. If, like me, you read this too late and are experiencing the Nigel O'Hara merry-go-round, be consistent and persistent and very firm. They are capable of refunding customers, just painfully slow.
